CAUTIONS DURING COMPONENT DISASSEM-
BLY AND REASSEMBLYGeneral cautions when cleaning
1. Clean each part, blow out oil passages and oil holes, etc.
with air and check that nothing is clogged.
2. For cleaning fluid, use the designated ATF (automatic
transmission fluid) or kerosene.3. When drying parts with air, be careful not to get ATF or
kerosene on your face.Cautions when handling parts
1. After washing the parts, arrange them in order so inspec-
tion, repairs and assembly can be performed properly.
2. When disassembling the valve body, store each valve,
making a group of the various springs.
3.Soak the new brake and clutch discs used for replacementin ATF for more than 2 hours before assembly.
General cautions during reassembly
1.Be sure to apply ATF to seal rings, clutch disc, clutch plateand rotating parts and sliding parts and then install.
2.Replace all gaskets and O-ring with new ones and do not

10. INSTALLATION OF CLUTCH PLATE/*. CLUTCH REAC-
TION PLATE
Assemble the clutch plate and reaction plate, arranging
them by the missing tooth [See figure
@I.
NOTEThis is so the automatic transmission fluid escapes easily
and there is good cooling of the plate and disc.
7. SELECTION OF SNAP RING
Check clearance between the snap ring and clutch reaction
plate. To check the clearance, hold entire circumference ofthe clutch reaction plate down with 50
N (11 Ibs.) force. If
clearance is out of standard value, select a snap ring to
obtain the standard value.
Standard value:
1.0-1.2 mm (.034-.047 in.)
2. INSTALLATION OF INPUT SHAFT
Align the input shaft oil groove and rear clutch retainer
